Secondly, and more commonly in the emulation scene, "repacking" refers to the modification of the BIOS for specific use cases. Standard Naomi BIOS files might need to be repacked or patched to function with "Net Booting" setups (loading games over a network) or to bypass specific hardware checks that do not exist in a software emulation environment. Furthermore, early or corrupt dumps of MPR-21931 may have been "interleaved" or split incorrectly. A repacker must de-interleave the data—essentially rearranging the binary code back to its linear, executable state—so that the emulator can read it linearly.
